GPR40 agonists stimulate insulin secretion only under the presence of high glucose concentration. Based on this mechanism, GPR40 agonists are believed to be promising novel insulin secretagogues with low risk of hypoglycemia. The optimizations of 3-aryl-3-ethoxypropanoic acids were performed to improve in vitro activity. We discovered compound 29r (DS-1558), (3S)-3-ethoxy-3-(4-[(1R)-4-(trifluoromethyl)-2,3-dihydro-1H-inden-1-yl]oxy}phenyl)propanoic acid, which was confirmed to have an enhancing effect on glucose-dependent insulin secretion after intravenous glucose injection in SD rats.

[EN] Pharmaceutical compositions containing arginine amides, peptides or analogs and methods for using the pharmaceutical compositions for modulating the activity of the FGF family of peptides are provided. Methods for inhibiting the binding of an FGF peptide to an FGF receptor by contacting the receptor with arginine amides, peptides or analogs of formulae (I) or (II) are provided. Methods for treating FGF-mediated disorders by administering effective amounts of one or more of these compounds or pharmaceutically acceptable derivatives thereof that inhibit the activity of one or more FGF peptides are also provided. [FR] L'invention concerne des compositions pharmaceutiques contenant des amides, des peptides d'arginine ou leurs analogues ainsi que des procédés d'utilisation de ces compositions pharmaceutiques pour moduler l'activité de la famille FGF des peptides. L'invention se rapporte à des procédés pour inhiber la liaison d'un peptide FGF à un récepteur de FGF par la mise en contact du récepteur avec des amides, des peptides d'arginine ou leurs analogues correspondant aux formules I et II. L'invention concerne aussi des procédés pour traiter des troubles induits par FGF par l'administration de quantités efficaces d'un ou de plusieurs de ces composés ou de leurs dérivés pharmaceutiquement acceptables qui inhibent l'activité d'un ou de plusieurs peptides FGF.
Bicyclic imidazole-4-one derivatives: a new class of antagonists for the orphan G protein-coupled receptors GPR18 and GPR55
A series of 23 novel benzylamines was synthesized by reductive amination from halogen-substituted 3- and 4-benzyloxybenzaldehyde derivatives and 6-methylhept-2-yl amine or n-octylamine. The antimycotic activity of the resulting amines was evaluated in a microdilution assay against the apathogenic yeast Yarrowia lipolytica as test microorganism. Promising compounds were also tested againsthuman pathogenic
